The secret stash is very very old but it is very hard o find Well to find it go to near the lake and keep going in any direction (stay near lake) and then you get to three thick poles that are stickinf out of the ground Then on top of the middle one and go up and right and you should find a weird building Go on it and there will fid abut 12 spiders
NOTE: You can als find it very close to Kinpins tower
